Just like LTE, LTE-M allows network connectivity and data transmission. However, the difference between the two is the simplicity of LTE-M – as it trades in data transmission rate for better power efficiency and signal range.
LTE CAT NB1 (NB-IoT) and LTE CAT M1 are new cellular technologies developed specifically for the Internet of Things (IoT) communications.
A major difference between 5G and LTE will be 5G's use of a higher frequency bands, operating at millimeter wave (mmWave) bands on the radio spectrum, in conjunction with lower band spectrum. That aspect of the 5G architecture will make great amounts of bandwidth available and overcome LTE's traffic congestion issues.
SIM800L supports General Packet Radio Service (GPRS) for connecting to the internet with HTTP. The module has built in TCP/IP stack that can be accessed with AT commands. This can be very handy for persistent data logging on low bandwidth networks.
A GSM/GPRS Module is a device or chip that is actually responsible for the wireless communication with the GSM Network. A GSM/GPRS MODEM is device that modulates and demodulates the signals from the Wireless Network and allows internet connectivity.
GSM was developed using digital technology. It has an ability to carry 64 kbps to 120 Mbps of data rates. Presently GSM supports more than one billion mobile subscribers in more than 210 countries throughout the world. GSM provides basic to advanced voice and data services including roaming service.
Quick definition: LTE Cat-1 is a variation of 4G LTE technology. Short for Long Term Evolution Category 1, LTE Cat-1 was standardized in 2008 as the first branch of LTE designed specifically for the Internet of Things. Cellular IoT has evolved significantly and LTE Cat-1 is still a popular choice for IoT manufacturers.
The current coverage for 5G is limited to high user areas but by adopting the LTE Cat M or LTE Cat NB-IoT standards, existing equipment can easily be migrated from legacy 2G / GSM and 3G / UMTS systems to 4G/LTE networks with confidence.
LTE Category 1 (Cat 1) is a replacement for legacy 2G and 3G. Cat M1 and NB1 are not far behind. These new, low-bandwidth technologies help many IoT networks expand capacity for surprisingly little money.
4G LTE technologies brought it additional spectrum and frequency bands, namely around 600 MHz, 700 MHz, 1.7/2.1 GHz, 2.3 GHz, and 2.5 GHz.smallest lte module
